Hi, i have a PHP error when logging in on the operator panel, the page shows HTTP ERROR 500 and the log:
[Tue Oct 11 08:00:25.187908 2022] [php:error] [pid 18212] [client X.XX.X:56682] PHP Fatal error: Uncaught Error: Class name must be a valid object or a string in /var/www/osTicket/upload/include/class.forms.php:1167\nStack trace:\n#0 /var/www/osTicket/upload/include/class.dynamic_forms.php(650): FormField->getImpl()\n#1 /var/www/osTicket/upload/include/class.queue.php(372): DynamicFormField->__call()\n#2 /var/www/osTicket/upload/include/class.queue.php(319): CustomQueue::getSearchableFields()\n#3 /var/www/osTicket/upload/include/class.queue.php(967): CustomQueue->getSupportedMatches()\n#4 /var/www/osTicket/upload/include/class.queue.php(901): CustomQueue->mangleQuerySet()\n#5 /var/www/osTicket/upload/include/class.queue.php(914): CustomQueue->getBasicQuery()\n#6 /var/www/osTicket/upload/scp/tickets.php(557): CustomQueue->getQuery()\n#7 /var/www/osTicket/upload/scp/index.php(17): require('...')\n#8 {main}\n thrown in /var/www/osTicket/upload/include/class.forms.php on line 1167, referer: http://X.X.X.X/scp/login.php
the administration panel is working but if i switch to operator panel HTTP ERROR 500
system is: UBUNTU 22.04, PHP 8.1, MARIADB 10.6.7 and was working flawlessly on osticket 1.16.3
